It's the combination of a few factors, really. On one hand, as Adamant pointed out, the use of stars for Favorite icons is pretty standard. It shows that something is special. The choice was also made to add circles around the voting buttons and favorite icons to provide consistency. Lastly, and this might be where the problem lies, the design does incorporate mystical elements. However, the intent is not to draw from existing religious influences, whether pagan or otherwise, but rather to employ generic "fantasy" sigils in addition to lines that look sort of sci-fi. As a result, yes, several of the icons look like they're some sort of alchemical diagram. Our logo has runes. However, the source of them is fictional and is not intended to have any sort of religious meaning.
So, long story short, no, you're not seeing things, really, but there's no intent to make anything genuinely mystical, and the star aspect is more incidental than anything else.
